    Ac and Dc Influence on the Pipeline From Zhongxian to Wuhan and Disposal Measures

    More Information
    • Received Date: March 29, 2007
    • There are many constructing sites of expressway and railway in parts of the natural gas pipeline from Zhongxian to Wuhan,and the pipeline is influenced by AC or DC from the earthing system of electro-equipment.Parts of the pipeline are crossing or paralleling respectively with many AC distribution power lines,and the pipeline may be damaged by strong current,and the AC influence voltage is more than 30 V in some part of the pipeline.The disposal measures aiming at these problems,such as electric drainage,surge protector device (SPD) and shielding line are introduced in this paper.
